23490-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23490-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23490-89:
(7*2)+(6*3)+(5*4)+(4*9)+(3*0)+(2*8)+(1*9)=113
113 % 10 = 3
So 23490-89-3 is a valid CAS Registry Number.
